Can I issue an invoice after the expiration of the consulting service contract?

You can issue an invoice, make a statement or postpone it.

Commonly used billing information refers to the opposite information that needs to be provided when invoicing. When issuing an ordinary VAT invoice, the other party's name and taxpayer identification number are required. Issuing special VAT invoices requires the full name of the other company, the taxpayer identification number, the address and telephone number of the company, the basic bank account number and the opening bank.
